RPG on the Portal.

Ink, you noticed some confusion among the undead... upon closer inspection, you discovered that far in the rear, another army of the dead is attacking... THE UNDEAD ARE ATTACKING YOU!!!
What will you do?

Wow, again! Finishing off the last of the living dead, we noticed reinforcements approaching on the horizon. Luckily, they were far away. Then I remembered the sage. Running to the battlefield, I didn't find him in the place where I had definitely seen him lying. Next to this place were the remains of a house. I went inside and saw an opening to a secret passage! Steps led down into the depths. Here I had to choose:
1) leave the city and escape through the tunnel
2) return for the remnants of the army and bring them here, abandoning the city.

It was impossible to defend the city. We had suffered too many losses. Everyone who remained was wounded. I was under a weakening spell. I could barely stand. The city must be abandoned. What a disappointment! But we will definitely return and take revenge on the enemy! Oh my god, what is that? A bone dragon was visible in the sky, hovering over the horde of undead! There is no question of defense! I need to inform my friends. Gathering my strength, I ran to the Stronghold and told the commandant about the underground passage....
