Witch Spelling

A fictional tale of witches, warlocks and wizards trying to fit in with the mundane way of life but always fearful of the consequences of being found out, especially after having already been persecuted and driven out of another town previously.
An accidental skirmish between two differing species, (both of which were once witches and warlocks) banished to adjoining worlds in an alternative dimension.
The chonguns had size and brute strength on their side but the rengans had some magic, even though it was somewhat limited.
There was no telling or even guessing if it did progress into a battle, if it would be a fair fight or which side had a better chance of winning.
