Nice effort put into this! Art was good, and writing was gernerally tight. (There were a few typos, for example a random 4, deceipt instead of deceit, etc.) I really liked how you could choose who to follow throughout, and the different perspectives were unique!
I know little of this time period, so I can't speak to historical accuracy, but a list of sources used would be nice (for nerds like me who like to fact-check, lol). But I'm pretty sure no one said 'okay' or 'reality check'. For the most part, the writing gave a historical feel without all the olde (sic) spellings and grammar. But there were a few, like 'okay', that really stuck out as being more modern.
Spoiler, if history can be spoiled.
At the end, I was confused as to what was actually going on. When it started, I thought he'd been poisoned, and they were counting the seconds till he dropped, lol. Then, at one point, the word 'lash' is used, which made me think whpping, and made me even more confused. Maybe just a mention of a flash of a blade would make things perfectly clear. :)
