"At morning light our swords did clash...nothing left but bones and ash"
(Skylord Vitali on James' death.)
Skylord James was a Skylord and resident of the Skyhold. He was secretly murdered by Israphel follower Vitali, who then hid his remains. Skylord James' tomb, along with other tombs, is discovered by Xephos, Honeydew and Skylord Lysander in Episode 29 of Shadow of Israphel. He was the only Skylord seemingly not killed by surprise, instead killed in a duel with Vitali.
Skylord James is never seen alive in the series, and very little is known about him. However based on the circumstances of his death he was likely one of the last to be murdered. His duel with Vitali seems to indicate he discovered Vitali's plot and was silenced before he could warn all of the (if any) remaining Skylords.
James seemed to be the more 'intelligent' of the Skylords as he was able to discover Vitali's plan. He also is likely one of the less experienced Skylords for he was unable to defeat Vitali in a duel.
