Provincal Campaign description

[caius britannicus]

This one has been a real noodle scratcher for me. I'm nearing the end of my long journey of making my Crusades mod. I'm currently writing up all the descriptions for units, factions and campaigns. Well units and factions I know where to look. However I can't find anywhere to write the campaign discriptions for my two provincal campaigns. Interesting enough I can edit the titles of the campaign in the campaign_description.txt using

{campaign_title}

however I cannot write any description for it there. I assumed the tag {campaign_descr} would do the trick but it doesn't seem to do anything at all. Does anyone know where I can. Description.txt in the campaign forlder does absolute nothing. So I am 100% stumped.
