Halie would offer to harvest the Fleece of the Lucky Ewe, "as my Gift will not upset the ewe as others' might." She would love to harvest Samhain's Judgement. And since she cares about Intellego she will insist on going to harvest the Glencoe Spring.
(If it's mentioned to her, Caoimhe will offer to find and gather up the Monster's Eggs.)
Halie won't be shipping her lab in until after the building on Eilean Chon gains a second story, and the first floor gets partitioned off (extra size doesn't do anything for a lab that isn't getting refined for virtues). I'm thinking that won't be until Autumn (and we may discover a regio for our labs, anyway). If Talia prefers to keep her shipboard lab then the other three new magi could all build their labs on Eilean Chon once the second story goes up. The two on the top floor would need to provide their own equipment, but the current guest lab has enough equipment to make two separate Size 0 Labs. If no one else objects, Halie would like to put her sanctum on the top floor, with no stairs to it. (I'd like to design this building if no one has any objections.)
