So, what are my options from here? I'm confused by this rather abrupt demise. I get that this is supposed to be high stakes, but it's a little pointless to kill off my character on his very first actual combat action isn't it?

After a cooldown period based off of in-RP time passed, you can app a new Servant if you're so inclined.

If a character is in a situation where the natural result is the character dying, then the character will die. I'll only fudge things if I think it patently mean, for instance killing someone in their first post after being summoned. In this case though, there wasn't any fudging; there were ways for Rostam to survive the attack, but they were not taken, so Rostam's death resulted. 

This sort of standard will be applied across the board, as well as to NPCs. For instance, if there was a "final boss" who had yet to reach their final form, and a player killed them on day one whether intentionally or not, then I wouldn't fudge things so that they somehow survived for no other reason than because I OOC want them to. Similarly, while I do want the players to win, if they were to wipe against the current boss for instance, I won't fudge things so that they somehow survive, even though them wiping means the roleplay ends and most of the work I put into the setting goes unused.
