OOC: Thargon will not ask for an Everburning Torch--he figures he doesn't need one, with darkvision.
So, that's 80gp for courtier clothing, and everburning torches are 110 each. Two torches and courtier's clothes cost 300gp.
Light noncombat horses are 75gp each. Saddles and bridles are 12gp each. Thargon can afford his own, so he'll just purchase it for himself.
Animal feed comes in at 5cp per day per animal, and rations are 5sp per day per person. 10 days' worth works out to 5sp per animal and 5gp per PC. For five PCs and a healer, that's 30 gp. If we all have mounts, that's 33gp.
Would a scroll of Mount be of value?
