The usual portion of the sailors get ready to man the firedust cannons if needed. As the ship rounds one wall, the weapons aren't needed, but they might be. The murals, from the small differences in sound the water going over them, seem to depict some kind of weapon using person and a strange animal fighting ... you're going to assume some kind of demon.<br/><br/>Pair of demons, now that the ship's moved some more. One with an air association, the other with watery ones.<br/><br/>"E-Entrance, ahead!" The call comes out from somebody at the far front of the ship. It seems that the ship can be sailed on in, although if the gates close, the ship will give way first.<br/><br/>In all likelihood, the murals are depicting some great victory for the original builders or owners of the manse. Presumably, the other sides have more of the story, or different ones. It's hard to verify from this distance.
