300 pt Spend - Getting it in before it's taken away!
Okay, here's my reasoning for expenditures. These are four Legendarily Wealthy Magi. What made them so wealthy? Did they already come from robust and rich covenants? I decided (and can be vetoed by Amul) that, since we're basically building these people, the Lannisters (Jamie, Cersei, and Tyrion) and primary Tremere friend Piotr Byrlaesh were an established, RICH magus family and covenant that were brought in primarily to back and banker Rafus. After expanding his base of contacts and resources, their departure for "conflicts of interest" would not severely hurt his relationship with his Cult, so Rafus let them go, planning to get revenge on them later for their abandonment. Unfortunately, he never got around to his vengeance before his (Rafus's) house of cards collapsed around him.
So, what would a rich, well-off group of magi be looking for? They've had access to plenty of books from their previous wealthy covenants, so they wouldn't have many primers (low level) books for Arts, and the few Ability Books they brought might be fairly esoteric based on their individual interests. They would wish to continue being comfortable in the eyes of their Society (magi) so it would need to be a location rich in resources. And preferably, somewhere their covenfolk could live well and not bother them too much.
This was to be a Haven, a place of rest and seperated from the battles and conflicts over religion and race for Moors and Muslims. Somewhere secluded and self-sufficient so, like a turtle, they could tuck into their own shells if needed to wait out large conflicts (like the Battle of ***********, will edit to correct battle name).
Side Note with 7 points spent on a Vineyards Manager specialist, I just had a neat idea - the current specialist is the WIFE of the old Vineyards manager that has taken over the job. Her Ability is still so high because she is "ghostly warded" and advised by her husband who died in the battle but returned to make sure she was okay and ended up staying (covered by the Boon we already have).
With this idea in mind, I leaned HEAVILY on Vis Sources (if they burned most of their vis and resources in the battle, why do they still have a stockpile of 100 Vim Vis? Did they have too much Vim vis and only sent what was feasibly carried?) and avoided anything but specialized books. And, of course, we have 3 Flambeau, so I added 1 Ignem book. 
Here's what I got

15 Creo 3 pawns, Spring -
15 Perdo 2 pawns, Fall - During the Festival of Sacrifice (Eid ul-Adha) on the 10th day of the 12th month of the Islamic calendar, several animals are slaughtered and the meat distributed amongst many - the covenant is known to invite other townships to partake or even to ship the food to close areas in need. Piotr Byrlaesh helped set up a magnificent slaughter stone platform with a firepit in the middle, blood grooves and head holes to assist in draining, and finely crafted blades inset into special areas on the table that conform with Dhabihah. The day is accompanied by a feast and festival around or in relation to the stone platform. In actuality, the slaughter meets with Islamic traditions but Piotr secretly added into the festival the practices of the Cult of Mithra from Old Rome. The Cult of Mithra acts to purify and cleanse the blood drained from the animals, and actually collected in areas beneath the stone platform. The firepit in the middle and the festival dancing lay the foundation for the blood to be boiled off, leaving behind blood dust and, surprisingly, 2 red crystals containing Perdo vis.
5 Rego 1 pawns, Spring
10 Aquam 2 pawns, Spring - Every spring the torrential rains and snow melts from upriver raise the level of the Guadiana. Flotsam and trash are always washed down from further upstream to get caught around the rocks and bends near the Covenant (about a half mile downstream), forming a dam and barrier. Every year, the covenfolk wade out into the rocks and waters to knock loose this trash since the increased water level begins waterlogging the soil and damaging the natural irrigation setup Old Man Mustafa(the old vineyard manager) had setup. The rocks themselves are slime-covered and in no way secure so it is easy to slip amongst them. Mixed within the trash is always several chunks of ice washed into the river from the mountain and still melting. The ice is almost supernaturally sharp and always submerged, which makes the task doubly difficult as it is easy to step on and accidently slice a foot artery, or fallen upon after slipping on a rock. In the past, people have been maimed or died after being sliced by these ice caltrops. The covenfolk prefer to wait until mid-spring near the point when the river is barely spilling over its bank, the water has warmed, the ice has all melted, and already washed downstream. However, the magi would like the covenfolk to clear the stream earlier and collect the ice chunks. Although most of the ice is dirty, misshapen, and pointed, there are always two perfectly formed tetrahedronal ice crystals pyramids that fit in a small child's two arms which are actually Aquam vis. On rare occasions these ice crystals wash down early and are nowhere to be found.
10 Corpus 2 pawns, Winter
5 Herbam 1 pawns, Fall
5 Terram 1 pawns, Summer
50 Vim 1 rook, Fall - can be smashed/broken in a specific pattern into 10 Vim pawns but requires a Dexterity+Finesse roll of +9. It can be transferred magically into new vessels normally. This sources is listed in the Covenant resources, but no details or manner of collection is given. If Jamie is asked, he states Cersei used to bring back a crescent stone mini-obelisk liberally covered in oil. It would have to be repeatedly dipped in oil or other lubricant and kept unexposed from air until the magi were ready to smash it or transfer the vis. He has no idea where she got it. There may be more details in her room or journal, but he is very reluctant to go rooting through her stuff or to let anyone else do so, for that matter. (He has already given up on the idea of keeping her lab pristine.)
Specialists Total: 30 pts
30 Points to be divided amongst 3 specialists
17 -(+2Com +7Teach +8Single Weapon) Weaponsmaster - Teacher. Abdul Fati bin Saladin, Captain, a Malmut that won acclaim and victory - but lost his left arm - in Saladin's Conquest of Jerusalem in 1189 - purchased and retired to Phoenix to train/teach shield grogs and turbs. Usually taught two students at a time. He has been called out of retirement after the death of most/all of his students at the Battle of Las Navas de Tolosa.
6 - (6 Animal Handling) Veterinarian/Animal Doctor. Farihah al-Kasim, a wandering goat-herd widow that settled in the hills north of the Phoenix Covenant. After helping deliver a breech birth cow on one of her visiting trade trips, she has moved close enough to run to the protection of the Covenant when needed, in return for assisting in any special care of the animals at the Covenant. She also helps supervise the slaughter of animals to make sure they are healthy and follow the rules of Dhabihah.
7 - (7 Profession: Blacksmith) Large (maybe Giant-blooded) Blacksmith. Noland (Naomi) Sepharad, a Jewish friend of Abdul Fati that accompanied him to Phoenix. Once a producer of swords and armor, he now happily produces nails, plows, nails, barrel rings, nails, hinges, nails, pots, pans, and nails. Okay, so he might not be so happy about the nails. Largely isolated for being an Outsider amongst Muslims, the few possible liaison attempts by daughters and widows were politely rebuffed. He seems to have no interest in females. Noland did not accompany the forces to Las Navas de Tolosa due to an illness and fever from exhaustion after staying up for five days helping prepare for the expedition. A moon later, when she was ready, it was too late.
