Dragons.
They were the top race of creatures even among the countless strong races in the Tower.
Dragons were considered absolute beings in the Tower; they were so powerful that the Tower deemed them taking tutorial a threat to others and only allowed the Dragons to start climbing the Tower from the 11th floor.
The majesty of a dragon was not something common people could fathom, with skills like [Dragon roar] [Dragon beam] [Dragon breath] [Dragon words] and such in their arsenal, they were beings who the Gods feared.
And one among such Dragons was now in front of them, and that to it was not as a climber but a summon, summon of a human at that.
Was there any record in history, of the arrogant and prideful dragons becoming a mere summon of a Climber?
Now that matter is considered, there were indeed such cases!
Undead Black Dragon, Ugram of the Crazy Necromancer.
Light dragon, Archrosis of the Supreme Summoner.
Ice Dragon, Chilalea, who protected the Frozen lands.
