Sigulf, you have reminded me of the first BoL game I ever ran, set in Simon's Lemuria (naturally), where the PCs used a build up of methane in the sewers of Halakh to explosive effect!

My reply to your question that I posted on Big Purple just now:

illustrations of the various creatures all had a man sized shadow next to them, to give you an idea of sizes. However, BoL doesn't really try to nail things down to the level that D&D did/does. And to be honest, I think that's not really necessary in a pulpy game like BoL. Just use your own judgement for your table. After all, the PCs don't wander the world with tape measures in their back packs.


Actually in the Ludospherik Mythic+ edition they do give a little guidance. A Ganuc (p.116) can 'comfortably sit on the palm of your hand' and the creature size is given as tiny. An Andrak (p.110) is a 'lion-like beast' and is given a creature size of large. A Parvalus (p.119) is a horse analogue and is also rated large. A Kroark is another riding beast which is rated large, and the illustration on page 118 shows it with a rider on its back. The illustration of a Poad on page 120 shows human figures next to this creature, which is rated Enormous. The Sarkolith on page 121 is rated Gigantic and you can see how that measures up to humans in the accompanying illustration.


I think if you hit your players with something above large, they have other things to worry about than judging how exactly big it is!


As Simon Washbourne has always said, if the text of BoL is silent on something, use your judgement and make a GM ruling.
 

Ahh, Tower of the Elephant - one of the classics, and one of the best starts to a Conan story ever!

I think there is a BoL adventure of TotE that someone wrote up and put on the internet for free. This was a good while ago (it might be written for Legendary Edition BoL), but you might still find it out there somewhere. 

The fourth session of my Warlords of Atlantis campaign started with Dina, Ralda and Mulius prisoners of General Selu-Ku, after a parley went bad. Dina had been attacked by Captain Chalan, the General’s son, and in the ensuing exchange of sword strokes she had unhorsed Chalan and then plunged her sword into his throat. Although Chalan had been the one to break the parley, the General had seen his only son and heir cut down in front of his eyes.
 
“See to my son,” he commanded the nearest troopers. “Captain Tisandros, secure the prisoners. We return to Fort Chania. For a cremation and an execution.”
 
The game was called ‘Prisoners’.
 
[These are 1 GM – 1 Player ‘duets’ I run for my wife Alison. I run the game with Bol + Sword and Sorcery Codex. The campaign currently takes place in the Moyturan colony of Utikan. Captain Chalan has attacked Prince Taras, heir to Moytura, who is visiting the colony, and his father has joined him in revolt. Earlier APs of this campaign can be found below, if anyone is interested. NB: This ‘episode’ is just over 2000 words long.]
 
On arrival at Fort Chania, Dina’s barbarian husband, Ralda noted that the fort was in poor repair, not only structurally but also with far too much vegetation close to the walls, providing cover for attackers. Captain Chalan had fled the capital with nearly all of the Atlantean phalanx, who’s men were devoted to him. His father had been sent to arrest him and bring him back to justice but had joined the revolt with most of the garrison cavalry. Utikan City had few troops left.
 
As the prisoners had been led into the fort the spearmen of the phalanx had jeered and spat at them. Only the protection of the cavalry troopers stopped them from all being slaughtered then and there. Captain Tisandros, commander of the cavalry, led the prisoners into the keep, and led the way down into the dungeon. The small procession was met by Chromis the steward, a plump nervous man, who led them d

Mage screws up spell and opens gate to other dimension. He needs to recover Arcane Points to close it (or get another wizard to do it) but before that can happen Scorpion Men come through the gate to check out what's on the other side.

Hilarity ensues.
