The Earth Dragon died during the siege by Renzo and the Undead.
However, as the primary enemy, Lord Serene did not perish, but was captured by Lind.
Until his defeat and capture, Lord Serene did not know whom he had lost to; he did not even recognize Lind.

Worried that Lind might harm him, Lord Serene took the initiative to inform Lind about how to control him, how to restrain his power.
And this "Lost Soul Knight Path Magic Potion Recipe" came directly from Lord Serene's oral instructions; it was also what he relied on to ascend to the Upper Rank.
