When you close the Cheydinhal gate and save the count's son, he will offer you one of the two family artifacts. That's the only one i know of.
Wanna good Blade? Visit Clavicus Vile's shrine, or even better Boethia's Shrine. Those blades would go nicely with Peryite's Shrine reward

About the gates: You don't have to close them all

Just the Main Quest ones. The way I pased the gates is by uisng my high Invisibility spell all the time, and eventualy stealing the sigil stone
