1 - As you enter the part of the forest where Sendai's Enclave is supposed to reside, you'll come across a woodcutter and his home. Speak with him to learn of a disturbance near his cottage. Agree to investigate, then make your way to area #2, where you'll be ambushed by a Hive Mother and several Drow. Once you've taken them out, return to area #1 to learn of some freshly dug graves near the woodcutter's cottage. Once again, agree to investigate, then make your way to area #3. As expected, you will be ambushed by a similar group of Drow. Kill them, then return to the woodcutter. At this point, the woodcutter will reveal his true nature by transforming into a Drow (along with all of the nearby animals). Once you've killed them, the door at area #4 will have opened to allow entrance to Sendai's Enclave. Before going, however, search the cottage to uncover the Rune of Clangeddin, used for upgrading the Runehammer back at the Abyssal Fortress. 2 - After speaking with the woodcutter at area #1, you will be sent here to investigate a disturbance. Once you arrive, you will be ambushed by a Hive Mother and several Drow. Defend yourself, then return to the woodcutter. 3 - After speaking with the woodcutter at area #1 a second time, you will be sent here to investigate some freshly dug graves. Once you arrive, you will be ambushed by another group of Drow. Defend yourself, then return to the woodcutter. 4 - Once you have killed the woodcutter and the remaining Drow, this entrance will open up to Sendai's Enclave.
