Tion Lannister
Ser Tion Lannister was the second son of Lord Gerold Lannister and Lady Rohanne Webber, and became heir to Casterly Rock after the death of his elder twin brother, Tywald.
His name became tied to an unexpected marriage: he ended up wedding Ellyn Reyne, the woman who had been betrothed to Tywald, in the same ceremony where his brother Tytos married Jeyne Marbrand.
