Teach my nation how to fabricate and use ropes and pulleys to lift heavy weights. They should be used to help the construction of the temple and big buildings. Tell them to refine it to be able to build both larger and smaller models, and push it to it's most extreme sizes possible while still being usable.
Spend more time within the nation, chatting and helping the locals with various tasks. Use this opportunity to determine if other cults are present and how widespread they are, and find anything the nation might have invented on their own. Visit the Huon the clothier from time to time and befriend him. Do not use any resources for the actions in this paragraph.
Also respond to the talking stone:
I am grateful of your gifts of wisdom and knowledge, as they surely help the various civilizations to progress. If you wish to help, then maybe you could explain to us how did an object managed to gift itself sapience? This is a very intriguing phenomenon, which deserves to be studied.
Reshape the talking stone to give it a somewhat humanoid, human-sized body made out of stone, but as flexible as a human would be. Make this process not painful and have no impact of his mind beyond giving him the ability to move.
Here, consider this as a reward for the gifts you gave to the mortals. You will now be able to move on your own, use this to spread your gifts further.
Edit:
And finally, address the ants I gave an increased intellect:
You should now call yourselves Beta Ants. I believe this gift I gave you makes you different enough from the other ants to justify a new name.
Use 1E to increase their intellect further and spread the gift to more ants, which will be told to meet with the other Beta Ants. Do not do this if it is going to need crux instead.
