Alright, let's see if you can do Irina. I'd like you to read the Writing Style Guidelines first. After that, make a copy of Irina's page on your Sandbox then start editing that copy. Does that sound doable?
You're on the right track in terms of information. However, you're going to have to put the new information on **Irina's page**, not Master of the Court's, since by this time Irina has already regained her past memories.
If the task is too big for you, let me know and I'll give you an easier one.
