Kyran would be lying if he said he was surprised about the Golden Dragon Tribe's request. At the same time, it was still something he did not expect. It might seem contradicting, but he supposed what he considered unexpected was how they wanted to keep it off the record.
Others might not think it was strange after what Kyran did in that day's match. Anyone would not want an official match against him if the chances of defeat were more than 50%. It would leave a bitter taste for their tribe's history or something like that.
But the one requesting an unofficial match was not just anyone. They were noble and prideful dragons. From this, their reason for it was not as petty as not wanting to taint their tribe history's good record. If this was the case, then the tribes Kyran defeated that day would have already done something to remove the black record of their tribe.
