All this time, the people of the Armeria Kingdom that they had colonized so far were very afraid and submitted to the Obsidian Sand Pack lycans because of Elias' cruelty.
If the people found out that Elias was dead, Eloise was sure they would revolt and the lycans of the Obsidian Sand Pack would be chased out. She didn't want to leave the power and good life she had, being the queen of Armeria. So, of course, any news about Elias' death during the duel must be covered up.
No matter how hard the spies from Riga tried to find out what happened to Leland, they couldn't get any useful information. It was like Leland and his men never even set foot on Armeria.
After trying for days and not getting any information, also not finding anything suspicious, the five spies decided to return to Riga and give their report to Noel. The head of the royal lycan hunters told Nicholas of their report.
