The last few adventures in my saga involved defeating an outlaw Magus (former member of the Order, thought long dead), and then retracing his steps to his secret lab on the island of Gozo, near Malta.
In the last session, the characters infiltrated a faerie regio, rescued a Magic creature that that Magus had trapped in order to generate a small magical aura, and defeated the fae Mermen guardians.
I had expected the session to culminate with rewarding the players with the Magus' loot, but the session went really long. We're starting the next session at the door to the Sanctum, and with one of the two Magi incapacited.
I expect that most of this session is going to be about gathering the loot, and then some seasonal downtime.
I'd like to have an obstacle or two in this session, however. I usually like to mix it up a bit at the beginning to wake everyone up, so I was thinking about maybe some sort of guardian or imp inside the sanctum? Or maybe some sort of puzzle or trap? I look to you all for ideas.
Some background on the Enemy Magus:
He's a Rego specialist, with stress on Terram, Corpus, Mentem, and to a lesser degree imaginem. His spells focussed on necromancy, mind control, and his terram spells usually involved Brass.
About 50 years ago, just before his gauntlet, he was used as a pawn in a centuries-old war between 2 rival cults. This brought about the destruction of his entire covenant. He was thought killed during the chaos, but managed to escape. The guilt and anger of being used in this way, however, made him go insane. He's been a sworn enemy of the Order ever since, and has been on the run for 50 years, changing his name and appearance when he needs to.
Some of his lab notes will be legible. Others will be the medieval equivalent of 30 sheets of vellum scribbled with "All work and no play makes Jack a dull boy."
So, I wonder what obstacles, guardians, puzzles, traps first pop into your heads?
Also, on a side note:
I was thinking that there might be some damage to some of the books he's been carrying with him for 50 years, especially some water damage from the sea air. If I lower the quality of a few of the books due to water damage, is it possible to re-copy the work in order to create a higher-quality book?
