I do belive I skipped around terrozing small pockets of every race and electing those worthy (read: not scared shitless) to be my champions and lead those I have touched. I am now telling my champions to build sall temples in the way I described above.
I thought you hadn't included them as a champion among useless blobs is still an useless blob, nor do they posses the means, physical and intellectual alike, to build temples. But yes, you've manage to force terror upon the hivemind and, as a result, all of the blobkin. As they are scared of you, yet haven't suffered from your acts, you did manage to get a sect of worshippers amongst the Devourers. Your worshippers basis will naturall grow with the population, as will Criptfeind's among the plagued ones, but the hive mind does not see any reason to usher them to worship you just yet, as it does not see you as a patron deity. Trust me on the matter though, they breed like the pest, you will get plenty of divine power.
Should you wish to actively expand your worshipper basis, either offer them a boon or bully them into it, although the later may invoke the wrath of other deities. As far as I am concerned, anything equivalent to your raising of champions, but compatible with the little blobs, will suffice to get the hive mind actively working towards increasing your worship. Also, to make it easier, I will have it so that the hive mind gets to it as soon you take an action; pulling it off as your first action wil afford you the vast majority of the 1000 years to come with increased worship rate amongst the Devourers.
PS: I really need sleep, I may have been needlessly confusing in these ramblings, if that is the case, just ask me again later.
