|Location||Sleeping Tree Cave|
|Reward||Ysolda will agree to buy Sleeping Tree Sap|
This miscellaneous quest is activated upon reading Ysolda's Message found on Ulag's corpse in Sleeping Tree Cave. The message details an agreement Ysolda had with Ulag to deliver Sleeping Tree Sap to her stall in Whiterun.
Ysolda will explain that Ulag was her supplier, but given his death she has no way to retrieve any more Sleeping Tree Sap. She will however offer to buy any that the Dragonborn may retrieve or find.
The quest is then considered complete.
Note: There are three quest stages and the second one in order is for failing the quest, but this does not mean that during the quest, it is both failed and completed.
