Each court has the same perks, aligning to one will just set you against the others. Here are the perks:
- Qeynos and Freeport Brokers, although they charge a slightly higher fee
- Mailbox
- Banker (and guild bank)
- Mender
- 1 NPC that will accept all reverse-writ items
- Merchants that sell levels 50-60 spells, artisan books, and special clothing. These merchants are the ONLY place to buy spells this level range, but you may find loot drops on the Broker.
- Already mentioned, lots of quest lines. You can eventually gain a Court-specific title, Vindicator of (court name), I think it is.
Even though Maj Dul is like a multi-level rat maze full of agro guards and patroling flying-uber-mage-cops, it is realativly easy to get around, ducking and dodging the dangers.
That's what makes the city so fun, a safe place yesterday may be dangerous today. Now that's fun gameplay!
When you do the Court quest to kill the captain of the guard in a nearby tower, be sure to listen for the celebratory bells at the end.
