"I took his blade and ran him through"
(Skylord Vitali on Finnigan's death)
Skylord Finnigan was a Skylord stationed in Skyhold, and one of many killed by the rogue Skylord Vitali. In Finnigan's case, he was supposedly run through with his own sword, then buried under an apple tree, along with Skylords Horus, Vimes, James, and the Unknown Skylord. His remains, and the remains of his fellow Skylords, were discovered by Xephos, Honeydew and Lysander.
It is likely that Finnigin's death was near the end of Vitali's killing spree, as Vitali could only have obtained Finnigan's sword to run him through with by engaging in a duel like Vitali did with James, which means he likely discovered Vitali's plot, perhaps with James. He was likely to be one of the more hot-headed Skylords, as he engaged in a duel with Vitali rather than telling the others, though it was also possible that he didn't have a chance to run.
