So, we're at 79,000 XP. The last thing Overman can do to improve himself at this point is get to level 8 as a fighter. That's 125,001 XP, which means getting about 135,000 XP from where we are now given the triple-class penalty (in practice closer to 110,000 XP due to the XP bonuses for high ability scores).
I could try the Nomad Camp, the Kobold Caves, the Outpost of Zhentil Keep, or Valhingen Graveyard. (Looting the rest of Yarash's Pyramid might have been fun but I am already loaded up with loot and I'm not actually sure I can make room for even 3 items at a time.) Areas with many waves are difficult for a solo character, and in the Outpost we'll be trapped until we exit, meaning we either stay for all seven waves or leave without getting all the loot. The Graveyard, despite the level-draining problem, allows us to leave whenever we want. So, we'll go with that.
As you'll notice, the sheer number of skeletons surrounding Our Anti-Hero allows them to do at least some damage. After dealing with the skeleton spectre and the zombie spectre, it's back to town to pick up our reward.
The graveyard is one of the few areas to 'regenerate' and have monsters come back if not completed. However, since the city council pays you a gold for every skeleton, a platinum for every zombie (including juju), and a gem for every wight (or giant skeleton), and a jewelry for every spectre (or the wraith), this can actually run to your advantage.
Oh, 'hair and fur'? That's a percentile roll of 56 on the random dungeon dressing tables in Appendix I of the 1st edition DMG. (They go up to Appendix P, 'Creating a Party', and include appendices on random generation of creatures from the lower planes, reputed magical properties of herbs, and the famous Appendix N which had the literary antecedents of the game.) Modern D&D players are familiar with random tables for magic items and monster encounters, but Gygax had random tables for trash you find lying around the dungeon, as well as (in the same appendix) air currents, odors, unexplained sounds, furniture including general, religious, torture chamber, and magic-user, descriptions of container contents, miscellaneous personal items, jewelry, food and drink, and condiments. Yup, there's a table you roll on to find if a jar is full of garlic, herbs, mustard, pepper, salt, or vinegar.
And, yup, there was a 'random harlot' table. I'll let y'all go Google that one as it's been reproduced ad nauseam, but this was part of the reason for the moral panic around D&D back in the 80s.
It's likely people actually liked this as part of the authenticity of the game--the monster portraits are drawn pretty obviously from the 1st edition Monster Manual pictures. The point was to play D&D on your computer, and, well, this stuff was part of D&D. Bowdlerized of brazen strumpets and sly panderers, of course.
