This is going to be one of many expeditions to places that are fairly lengthy. My experience with the Beginners' Guide to Daggerfall suggests that a picture is worth a thousand words, so I'll do some of these as maps rather than written directions. However, since my bandwidth is somewhat limited and graphics eat up more of it than text, I will try to keep the graphics to a minimum. Fortunately, most "dungeons" are fairly short. So written directions will suffice, the bandwidth will be preserved, the bank account won't be dinged any more than necessary, and there will be much rejoicing.
There are seven sections to the Urshilaku Burial Caverns, but you only need to go through four of them to get to your destination. This is not to say that the other three are not worth exploring, but that they are not critical to your success.
Aside from the items on your map, there are two mummies (dead, not undead) with Chitin spears near the wilderness entrance.
Up near the where the two containers are next to each other, you should be able to find a couple or three Skooma potions.
Providing a readable 2-dimentional map for this 3-dimensional space is difficult at best. What you are wanting to do is make your way up the winding ramp to the top of the chamber where you'll find a door leading to Juno Burial. There are no creatures in this chamber, so you won't be fighting anything. There are several very nifty items placed here, but getting to them is a major problem. A Levitate potion or spell is a requirement if you want to do anything other than get to the other chambers. In no particular order, you should be able to find:
Glass Greaves
Demon Helm (non-enchanted Light Armor)
"The Four Suitors of Benitah" (raises Restoration skill)
"Silence" (raises Illusion skill)
Amulet of Frost (1-25 Frost damage on Touch)
3 Urns with potion ingredients
1 Urn with spell scrolls
1 Small Chest with gems
Magebane (Glass Claymore - Resist Magicka 20-40 for 10 seconds)
Ebony Wizard's Staff (required for promotion in the Mages Guild)
You'll find the bow on Sul Senipal's remains after you dispatch him. Elsewhere in this section are a few minor items: a standard Fortify Magicka potion, a quality Frost Shield potion, some Dreugh Wax, a common Soul Gem, an Apprentice's Probe, a Journeyman's Repair Hammer, an Iron Sabre and a Steel Dagger.
After you have the bow, report back to Sul Martuul and he will name you Clanfriend and send you over to the Wise Woman, who will now be willing to talk about the Nerevarine. Click here to go back to that page.
