Ghosts are some of the easiest -and- hardest fiends Penelo's dealt with. If you're lucky, all it takes is a strong enough healing spell; other times, you have to get creative.
"How much longer do you think that you will succeed in delaying the consummation of your-- arrangement with my brother?"

Penelo almost pretends the crate of dark magicite is a gift. Larsa's given her a little, incredibly expensive something every time she's spent a few nights here-- but the guilt on his face tells her that he knows exactly why she's brought it.
"I am sorry. I will speak with him."
Which is fine and all-- she trusts Larsa to do it-- but Penelo's learnt a thing or two about Archadian negotiations.
The magicite rings each of the suite's rooms before they go to bed, and as Penelo lingers awake on too soft linens, she hears something scratching, but it's outside the window.
