1. Yes Enadyo (and the other heads) should probably occupy more squares. I'll just make the bride a bit wider.

2. Yes the Knowledge Arcana is going to identify the golem, Actually most golems aren't immune against magic in this game, because they are not magic immune in the Secret of mana games this game is based upon. Some are but they basically scream (immune against magic) into every casters face (it's a design thing.)

3. Yes you can put you're familiar into an adjacent square. Though he's not an Oslecamo hellhound, just a "normal" one. (As far as hellhounds can be normal)

4. Direction of travel was in the direction of the golem.

5. The bridge is over a chasm, but it's too deep to see if it leads into water. (It could be! Or lava. Or magical healing mist. Only one way to find out.)
