posted by a US GM on June 3:
The "Perm pet" content has been added but it did not say new perm pets were going to just show up in game or in the item mall right after the patch. Please be patient for this.
As for the Runetowers...well, I can't find them either. I will see what information I can gather in regards to this.
Sorry for the inconvenience. 
here is what Runewaker has to say about what is coming in the future: Upcoming Changes
