Some werewolves savaged some Men, I killed them and healed the Men, and then a bunch of the werewolves all ran off home past some sort of invisibility curtain. I threw a rock at it. It stopped at the curtain and a fellow walked out with it in his hand and we had a... conversation. It was Thauron.
Hug. I kept him talking for a while. He wanted to bribe me. Offer came with a free sample. It's the orcs. He offered to stop them hurting all the time. I talked the free sample from six days up to twelve but I'd have to give him stuff to get further increments and I'm not going to. But leaving the Men there being ignored by their Nandor neighbors and courted by Thauron seems like a bad idea, which is why I came here; they'd be your father's people too, wouldn't they?
Well, I killed a Balrog but Thauron seems likely to be out of my league and I'm not sure who else would be helpful and would come.
I'm not sure I have the right to take that risk without some kind of ace in the hole.
We could invite the Men to come to Beleriand, tell them there's no werewolves here. I don't know We aren't much like Men, I don't think we'd be very good at guiding them. They're not meant to live in trees, for one thing, and they don't sing themselves the things they need and couldn't rely on us...
And I'd have to go tell them that and Thauron expects me back to continue employment negotiations in eleven days and may be laying an ambush if my first words aren't "so when do I start".
It's a long trip if you're not a bird, and I'm not sure how much support they can provide against a Maia. The suppressive fire some of the newcomers' archers provided when I fought the Balrog barely annoyed it.
I probably cannot train you to be good at it in eleven days minus travel time.
