Mari Pax Sol - or Mari as they more commonly present themselves, is a changeling traveling through the Forgotten realms. Originally raised in the Dragon monastry, but in their teenage years having left the place, the changelong monk posseses great skills in stealth and subversion. Their main form - Mari - spent the following years after leaving the monestry at the Lamplighters Guild, developing the skills they posses today. 

Having the ability to shift their form, they became adapt at trickery and thievering. But the shapeshifting abilities had other qualities.. and as the main part of their training was spent sharpening the mind, made them later in life able to shift between different aliases. 

As of today, they feel most comfortable in their main form - Mari - human form - monk. 

But they've been known to shift to either Sol og Pax, whenever their alias are threatened or their life in danger.
