So I have a few suggestions for Guild hall related things.

First is:
A 3x3 squares statue of Margrel that you can get somehow, or perhaps make at the Mysterious Alchemy Machine, during the Kataclysmic Confrontation event.

Secound is:
An interactive book stand, that you can write a bit in. So if you have it at the entrance, you might want to write guild rules. If you keep it in a chess room, you might want to write up the basic rules of chess for those who don't know. The imagination is the limit here.

Third is:
A Hnefatafl Board room. So, we already have a chess room, and pieces that work perfectly for the task. So why not create a floor that fits for Hnefatafl too. The current amount of squares on the floor is perfect for a small(9x9) Hnefatafl board, though if it is possible to make the bigger(11x11) Hnefatafl board that if more fun to play.

So what do you think? Do you have any ideas of your own, or ways to improve these?
