The Binding

By retrieving my choker and besting Surena, you've proven that you're at least as capable as she was. With that said, I can tell you're direly in need of training. You can manage the flows of magic, yes, but being a warlock is much more than that. I will show you how to command a voidwalker, but before I can, you must call one forth at a summoning circle and subdue it using whatever weapons--physical and magical--you have at your disposal. Use the magic of this choker at the summoning circle below.

You did better than I expected, <name>, but as well as I'd hoped. Now, you can learn to command your subjugated voidwalker, an ally you will find valuable in the trials that are sure to stand before you. I have nothing more to teach you at the present, but I am far from done with you, <name>.

Using the heartswood core, you will be able to cast a spell at the summoning circle in the crypt below to open a portal for the succubus to pass through. Be careful, <name>, succubi have overrun even the strongest of minds. Once you have bested and returned it to the void, return to me and I will show you how to call and control it.

Well done, well done, <name>. I see we've done right in deciding to train you. Your performance certainly does not disappoint. I've no qualms in showing you the way to control your newly bound succubus. Observe carefully.
