So for Heron I think we may have discussed some stuff in the past? I have Pyr, my squire, to get up to no good around him; I have Mags to maybe know (of?) him through Rictor, idk, and I have Toku for old men things BECAUSE OLDIES GOTTA STICK TOGETHER.
As for Lena, I think my bets would be Mag who's from Anjou too (but might not know her all that well if at all? idk, up to you) and Loch who I think would definitely know her since Loch and Ash have been friends for many years now and I imagine Loch's dropped by Ash's workplace at some point to pick her up after work or whatever, something, ANYWAY she could also have done some work for Lena in the past, maybe security stuff (she does traps!) or poisons (modifies weapons too, with some restrictions) or basically anything you'd like, we can figure it out! :D :D
