Name: Colin

Captured while patrolling Akidu Valley after taking an Orc Morphing Potion.
Imprisoned in a holding area under the Valley and left unattended.
An Akidu soldier fed him grass from around the prison.
Survived for 6 days by eating the grass and rainwater given to him by the orc.
Ate some kind of grass to clear the morphing.
Used a stone and rusty nail in the prison to open the lock.
Escaped the valley when the orc was negligent in watching him.

Note:

What kind of grass did he eat?
Looks like mugwort. It has a pungent odor and a strong bitter taste.
Need to identify the plant ★★★★★
