Thanks guys!
May update:
- added more encounters to the existing areas, including several "wandering monsters". These are (sometimes) optional encounters that move around on the map so are rarely in the same place twice, but can't be seen. I still need to fully check a "flee" mechanic in relation to this, which Karl gave me some help with on a different thread, as sometimes these wandering encounters can completely outlevel the party and its wise to avoid them early on;
- started mapping out two of the three new areas that border the main completed area;
- added several new convos to the opening areas;
- added in a "detect secret" skill, which is used for finding secret doors and buried treasures etc, and then added in both a secret door and a buried treasure

;
- completed journal entries for all the quests that can be initiated in the early areas.
So slow progress, but progress!
