That would work. And you would also know that he is scary beyond all reason and imagination. Many of the traps around his lairs are those that blast the intruder with negative energy. He has well over three dozen offspring, very powerful in their own right, as well as hundreds of half-dragon children. He also has fifty dragonkith (normal people that supplicate themselves to a dragon and gain some draconic abilities, it's a PrC in the Draconomicon), as well as many shadow-tainted dragonkin in his stronghold. He's a scary, scary dragon. The only reason you did escape is that you were tending to out of his outer-lying strongholds at the time. It would take people with many, many more skills and much experience to infiltrate Sssarendor's personal lair.
You would also know Guran, one of the Sssarendor's sons that was born in the camps of the resistance when his preganant mother's caravan was captured.
