Map #39 – Consortium Hideout

A quick OSR-ish map. There is a small crypt, perhaps underneath a ruined temple that has two secret doors, one of which leads to a small underground compound of the Consortium. However, the other door leads to a small, trapped room with a fake door on the other side.

The compound itself has a small hidden harbour, just large enough to take a small boat out to meet a larger ship.

Here’s a version without the text and one without the grid.

Map #37 – Narrow Pass

Here’s a small map featuring fortifications on a narrow mountain pass. The dwarves (?) put up a valiant fight defending a remote pass but ultimately, the orcish (?) horde proved too powerful.

The players could pass by just hours after the defenders were defeated encountering a couple of attackers left behind. Another way might be to have the players actually defend against the attack

There’s also a black and white version available.

Map #36 – Destroyed temple

Time for a quick OSR-ish map. The temple of N’Xroth was destroyed decades ago, but locals claim that evil spirits still linger. Perhaps the purge wasn’t as thorough as the Order of the Crimson Dawn would have hoped.

If you prefer, here is version without the grid.

Map #35 – Castle Dread Dungeon I


Some time ago, I drew a castle/monastery that I called Castle Dread. That map had a couple of access points to lower levels and here is one suggestion for what those might contain. I have a couple of thoughts about the rooms, but feel free to substitute as you wish.

First, the main burial chamber has been sealed off. The wall can be determined to be new with an easy perception/etc. check (adjust to your system). Inside you might have either an empty grave or a reanimated corpse of a noble.

Then there are a couple of secret doors. This part of the dungeon contains a few “preparation” rooms, a watch point overlooking the sea and a couple of holding cells. There is also an elevator leading down (I hope to draw the second level later).

Here is a black and white version, if you prefer that.

Dice math – What’s the difference?

Content warning: Sloppy statistics and a chance of horrible mistakes.

One interesting question regarding various mechanics is ‘How long does it take to figure out who is better?’ Characters in the world don’t observe each other’s bonuses but rather the results of the checks and checks have a random component in them. So it is very much possible that a more skilled character loses multiple times to a less skilled one. Luckily, we can use (or abuse) a few methods from statistics to take a stab at this problem.

Map #34 – Underwater Shipwreck

A ship carrying valuable cargo was attacked or just sunk due to unfortunate weather. However, the (undead?!) crew managed to salvage most of the cargo to nearby caverns. The players might want to loot the wreck out of sheer greed or perhaps the ship was carrying a cargo that was imperative to whatever world-saving they’re doing.

For foes, you can use whatever aquatic creatures you want or as I initially, thought, let the ship have an undead crew that is still patrolling the area and guarding the cargo.

However, be careful not to disturb the kraken!

Here’s also a black and white version.

Applied fantasy math – Vampire populations

Some time ago, I became aware of a nice paper – The Transylvanian problem of renewable resources by R.Hartl and A. Mehlmann. You can find an ungated copy here. The paper itself is quite technical and I’m not familiar enough with optimal control theory to fully explore it here. The idea of the paper however is to consider a vampire population feeding on humans and find optimal feeding strategies for different discountings of consumption.

Map #33 – Castle Dread

Back to ink-only maps. Castle Dread might have started as a monastery or a chapel a long time ago, but due to its location on the coast, it was soon upgraded to a small castle to keep an eye on the marine traffic passing by. However, the castle has has been abandoned longer than anyone remembers. It is still in relatively good condition, but most people stay away from it. Even hardened bandits haven’t made camp there. There are two secret trapdoors that lead to catacombs beneath besides the obvious stairs inside the chapel.

Feel free to place any monsters – or mundane foes into this keep. I will add dungeon levels in a separate map later, but unfortunately, you will be on your own on that front for the time being.

Here is a black-and-white version without the grid.
