Re: Mount quest eogar letter
To get a permanent horse and not just a time limited whistle, you have to buy it from one of his farmhands.
The first horse will cost you 500s. You'll also need to get the riding skill to ride the horse. If you're VIP, you can get a quest at lv20 which grants you the skill on completion. Or you can just buy it from the LOTRO store for 95 TPs.
Whistles can also be bought from the LOTRO store if you want to, but all of them have a time limit.
