But Godric never liked it that he was allowed to have the basilisk in his quarters. Everything went downhill between Godric and Salazar, when a group of muggles, who had tried to attack Hogwarts and had the intention to kill the students, were killed by the basilisk. Godric was furious and told Salazar that the basilisk had to go with Helga agreeing, but Rowena was disagreeing with Godric and questioned him, what these muggles were doing here with their armour and why they did have exorcism materials in their bags. This set off into an argument between the founders. Rowena and Salazar were fighting with Godric and Helga, but Rowena came to a conclusion to build the chamber, where his familiar could stay. Salazar was supportive, but Helga and Godric were a bit miffed, but begrudgingly agreed, since the chamber was a better idea than Salazar’s quarters. Salazar made it clear that he would rather die than let his familiar go. Their friendship was from there on a bit strained. That explained the Gryffindor-Slytherin-rivalry and conflicts between Ravenclaw and Hufflepuff. It had taken years that their friendship was fixed, because it didn’t make sense to fight about his familiar and Godric and Helga had admitted that they couldn’t separate a wizard from his familiar. So, they made up and returned back to their old ways.
