Alehouse Notice Board

Foreign Service

Details - Objectives
Acquire 20 Seeker's Tokens
Region: All Gransys

Reward: 200,000 G

Request
A court official from a neighboring land has curious tastes and a deep purse. See that their desires are sated.

Seeker's Tokens Locations
These will be found in chests and crates across Gransys, including in Gran Soren. A good strategy to get this is to loot everything in Gran Soren whenever you are in the capital. Also, you could try giving one to Mountebank in Black Cat, to forge. Although that could turn out expensive. Report to the Arsmith and hand these over once you have collected 20 of those.

Reveille Revelry

Details - Objectives
Acquire 50 War Bugles
Region: Gran Soren

Reward: Soultaker x I

Request
The horns the capital guards sound are lovely, and their call as clear as a pure spring morn. I would have one of my own.

There are some War Bugles in Gran Soren and in the Encampment, but the best way to get most of these is by doing the quest Final Farewell in the Encampment Notice Board (which gives you 40 War Bugles as a reward). You can also try and have Mountebank forge some, if you are missing a few. Go back to Arsmith at the Alehouse and give him the War Bugles once you have gathered 50 of these.
