Editing, corrections, and filling out the wiki and knowledge base

I tried to add "Power of Runes", but my cards go vertically instead of horizontally, and I don't understand how to add "Pages linking here".

They are generated automatically — you just need to go to another page that will link to it, add a link somewhere in the text using the same "Link" button, and select "Link to wiki page".

I added your page here https://heroesworld.ru/wiki/heroes-5/%D0%B0%D1%80%D1%82%D0%B5%D1%84%D0%B0%D0%BA%D1%82%D1%8B/

<a class="wiki-link" data-wiki-page-id="21980" href="/wiki/heroes-5/artifact-sets/сила-рун/">Сила Рун</a>
