In reality though, it's just a bad splice I made years ago (back when I tried to sprite).
How does that relate to Percival at all? Well, Pellinore is implied to be Percival's father. The mythological Percival, one of the Knights of the Round Table, was one of King Pellinore of Listenoise's illegitimate sons (five of whom joined the order). Etrurian Percival's father shares the name Pellinore with Percival's father from Arthurian mythology. Therefore, Percival's father was the Great General before Douglas, whom Percival succeeds at the end of FE6. A bit of mythological referencing to add some depth to one off-handed comment.
