The Tower- Second Floor

I'm afraid the flask is a decorative one, not a hipflask; more a container for mulled wine or something waiting to be poured in a palace.

The Sun Stone in the jewellery box does emit unusual energy, but as I'm pretty sure neither Hotaru or Phil are secretly pokemon, I doubt it affects them.

The chainsword changes, the casing turning the glossy black of a beetle's carapace, the teeth becoming shiny white shark-like teeth. The words change, too, to THE GREAT DEVOURER. Whoever holds it, gains telepathic control over most standard insects, and also protection from mental attacks by psychic Tyranids and also acts as a synapse creature, able to direct any Rippers or Gaunts they may come into contact with... Unless a true Tyranid synapse creature is close enough to control them, anyway.
