[Grundy is seated, as he begins to calmly explain past events to Angharad.]

Everything around it is dying, slowly but surely. The grass, the birds... even my crops are wasting away at the bottom of the hill, now. The field workers are scared shitless, won't go near the damn thing. Last week I relented, and thought I might cut the accursed thing down. But I couldn't even raise my axe... like the strength had been sucked clean out of my arms, at the mere thought of it. I was never a superstitious man before that, but... there's something terrible beneath that thing's bark, sister. 

[The horses are spooked by something unknown, and Grundy sternly addresses a stable boy as he struggles to maintain control.]

Secure those horses, boy, lest we lose any hope for this damned place!
