Sahuagin Treasury Key

This key is on King Ixilthetocal's person, who is encountered in the Underwater City during Baldur's Gate II Chapter 4.
==Description==
==Gameplay==
The key can only be obtained by pick pocketing or by recovering the key from the Sahuagin king's corpse.
The king will never give the party this key, even if they fulfill the king's wishes as part of The prophecy of Sekolah questline. Instead, the king provides some item rewards. The Saughain treasury is never opened for the player.
Of course, a nimble-fingered party member might obtain this key from the king and access the treasury's contents.
If the party sided with Prince Villynaty and the king is killed, the prince will at some point say:
:"We owe you a debt, <PRO_RACE>. We are unfamiliar with your kind, but you are welcome amongst us. And you did more than was asked, bearing the brunt of the battle."
This is followed by:
:"For that, I give you the first spoils of war. Take the treasury key from Ixilthetocal's corpse... use it to enter the city's treasury and take what you will."
