Took a look at the two Luther Arkwright supplements for Mythras by Design Mechanism. Few of the creatures there would suit fantasy campaigns especially Monster Island so created them in Mythras Encounter Generator.

Here is the introduction to Mythras Encounter Generator. It currently contains more than 3800 published encounters and more than 580 parties (groups of NPCs around a single theme). There are more than 400 feature lists (for example Curse Spirit Ability, Exotic Poison, Chaotic Feature, Medieval German Name or Appearance – Hair Style etc) that can customise an encounter. Those feature lists contain almost 60000 features in them. There are also stats for 160+ weapons.

Created few different kinds of ancestor spirits to replace the old ones. Balanced has spirits, spells and ancestor skills and even discorporate if intensity is enough
Spirit Guide usually has spirits and discorporation. Shamans usually has spirits only but on higher levels also discorporation. Sages have skills
Withces and spell casters have folk magic.
I updated the Monster Island shamans to have the above instead of old ones. Each tribe has high shaman, shaman and spirit worshipper levels.

Design Mechanism published a mighty tome called Mythic Babylon this summer. It contains magic system additions and everything necessary to play a role playing campaign in Babylon – of course including creatures.
I have added a few of those into the Mythras Encounter Generator so it will be as easy to generate those than any others. There are also few additional abilities for beasts – Good and Bad Omen, Melammu – a form of frightening splendour and See Ghosts. These have been added as abilities to the MeG.
I have also added tag “Mythic Babylon” for existing creatures that I have created that might be encountered in Babylon.
First batch of new creatures are
These could also fit nicely into a sword and sorcery campaign for example Monster Island.
There are already aurochs, Babylonian ostrich, Cheetah, Common Griffin, Hyena, Jackal, Lions and Wolves to fit into your Babylonian campaign.

Sorcery Calculator has been updated to handle invocation skills up to 400% and shaping skills of up to 400. These major skills are usually available with orchestrated casting of certain sorcery schools for the invocation but might be available also for some superbly potent individuals.
This now also includes the alternate names for spells in Monster Island sorcery.
Some of the spells do not have enhanced effect beyond 120 in skill but almost all do.
Protected by minions these highest level sorcerers are truly potent opponents as they should probably also be played like the most intelligent enemies in the realm.




Some spell examples with the skill and shaping chosen
