A Desert Dwarf found the Dwarf King and accused the Laine Empire of stealing his goods. This merchant was a relative of the Dwarf King, who, without any investigation and in a fit of anger, ordered his troops to attack.
In a surprise attack, the border outposts of the Laine Empire were breached, many humans were captured, and lives were lost.
Once the army invaded, the nature of the dispute changed completely.
From that day forth, the Laine Empire formally declared war on the Desert Dwarves.
Hoffman Ironfist had felt something fishy about the situation from the start. Although the humans of the Laine Empire were very arrogant and barely glanced at other races, their faith lay in the Lord of the Dawn. They would discriminate against other races but would not break their own rules out of discrimination.
The goods were unjustly taken?
Such an incident might seem plausible elsewhere, but happening within Laine's borders, it was highly irrational.
