TAKE X (6-5-17: The End)

Sienna: Step one, remove the biggest threat. Render the One Goddess powerless. This way, if she realizes what you're up to, she'll be less capable of standing up to you; and, if one of your "allies" discovers you before you're done, you can bluff credibly if you only made that one change.

And maybe hide a big deposit of gold or something somewhere that only you can reasonably access. You know, as a plan B.

Palmer: Maybe now's the time to check out that door that was bugging you before. The thief might be hiding there.

This is totally not a thinly-veiled excuse.
