It's Mak'Gora, a duel to death. Before your brother accept the duel he received a warning message that in case of losing the duel, the character will die permanently and also wrote "I accept" in the box so the duel to death can begin.
There is no possible way to resurrect your character. Maybe in the next holidays, administration will be generous and it will revive all dead characters (like it happened on last holidays).
