Added some descriptions and did some minor edits. It’s not that hard, everyone should try 
Editing old articles is a bit research intensive since they mention some stuff that is not in game anymore, like broken stone, stone chunks etc.
For anyone who wants to contribute here are some useful tips:
- this is the list of all the articles in wiki https://boundless.gamepedia.com/Special:AllPages
- to edit page there are two buttons in the top right corner of page content “Edit” and “Edit source”, former is used to re-arrange page elements to positions (i.e. layout) and later to edit actual page content i.e. text, add images etc
- to put page in a category just add [[Category:Creatures]] anywhere in page text, replace “Creatures” with any category
- to add link just add [[Linked_Page_Slug:Linked Page Name]]
That’s about it for now
Happy editing!
