If that is not possible the next step depends on the nature of content in question has been added relatively recently (arbitrary cut-off date: all content newly added after 01 August 2024) feel free to immediately revert or delete the unsourced content in question.

If you do feel generous or if the content in question has been added before the cut-off date mentioned above you can first try to find a corresponding, valid source. If that is not possible the next step depends on the nature of the unsourced/ insufficiently sourced content in question: *Case 1: If the unsourced/ insufficiently sourced content is a generally known "fact" (e.g. "Orks are green") or seems probable enough proceed to mark the content in question (including eventual sources) as explained [[Warhammer_40k_-_Lexicanum:Citation marking|here]].*Case 2: If the unsourced/ insufficiently sourced content suspiciously looks like for example fan-made content(e.g. a romance between an Imperial assassin and an Eldar farseer), false information or otherwise very highly dubious information, proceed to [[Warhammer_40k_-_Lexicanum:Quarantine|quarantining]] it. Please do note that this step should not be taking lightly as quarantining parts of articles might do serious damage to their readability. If in doubt, discuss the issue with fellow editors, [[Warhammer_40k_-_Lexicanum:Administrator|Administrator]]s or [[Warhammer_40k_-_Lexicanum:Bureaucrat|Bureaucrat]]s.
