The final Making and Mending project required construction. Not a wand. Not a magical weapon. Not anything Harper had hoped for. A shelter. Professor Ward divided first-years into groups of six and took them to the inland practice lawn. Each group received poles, rope, heavy cloth, wooden pegs and a small set of approved reinforcement charms.

"Build something that keeps six people dry under simulated rain and remains standing under moderate wind."

Harper looked at the pile.

"Can we use magic for all of it?"

"No."

"Why?"

"Because if your reinforcement charm fails, I would still like the roof not to land on you."

That sentence sounded familiar by now. Jasper's group included Harper, Ava, Mia, Theo and Soren. This was either ideal or a punishment for Professor Ward. They had ninety minutes. Ava immediately tried to plan the entire structure. Harper immediately started moving poles. Theo immediately hammered a peg into the wrong place. Soren read the knot card. Mia said, "Stop. Everyone stop." Everyone stopped. Mia looked surprised by her own success.

"Ava, plan the base. Harper and Theo, don't touch anything until she does. Jasper and Soren, ropes. I'll check cloth."

Harper said, "Why are you in charge?"

"Because I said stop and you stopped."

Harper considered.

"Fair."

The first twenty minutes went well. Then the wind shifted. Their rectangular shelter became a sail. One pole leaned. Jasper grabbed the rope.

"Need another anchor."

Ava said, "That changes the geometry." Harper said, "Good. Current geometry is falling." Ava adjusted. Second anchor. Soren tied it. Ward called, "Less!" Theo reinforced the peg with too much magic and cracked the soil around it.

"Sorry!"

They reset. The shelter stood. At the forty-minute mark, simulated rain began from enchanted pipes overhead. Water hammered the cloth. A leak formed directly over Harper.

"Why me?"

Mia laughed. Jasper used a simple sealing charm on the seam. The leak moved half a metre and dripped on Soren.

"Why me?"

Harper said, "Justice." They reinforced the central ridge. Ava noticed one rope taking more load than the others.

"Shift this peg twenty centimetres."

Harper moved it.

"Not thirty."

"It is dirt."

"Twenty."

Harper moved it back ten. The load evened. Jasper thought of the storm barge. Ropes under pressure. Systems working because nobody relied on one line. Their shelter passed wind stage one. Stage two pushed harder. One side lifted. Harper physically held the pole down. Ward blew the whistle.

"No human anchoring."

"It worked."

"If your design requires Harper permanently attached, redesign."

The group laughed. They added another guy line. Stage two passed. Then Ward introduced the final condition.

"One reinforcement charm fails."

Every magical support on their north side vanished. The shelter sagged. Ava shouted, "Manual ropes!" Jasper and Soren tightened lines. Harper reset the leaning pole. Theo held the cloth clear while Mia re-pegged the corner. No advanced magic. Hands. Knots. Communication. The structure stayed up. Ward walked around it after the test.

"Ugly."

Harper said, "Rude."

"Stable."

Harper brightened.

"Good."

Ava looked at the mismatched peg spacing.

"Could improve."

Mia said, "It's standing." Ava breathed.

"Yes."

They ate lunch inside their shelter. That was the reward. Sandwiches tasted better when eaten under something you built, even if the cloth roof leaned slightly left. Soren opened a book. Harper took it away.

"No. We built a shelter. You have to experience shelter."

"I'm inside it."

"Without book."

"Why?"

"Respect."

Soren looked at Jasper for help. Jasper said, "She's impossible." Not a spell. Not a gate. Not a friend. All three were right.

Soren took the book back. The project became one of Jasper's favourite memories of first year. Not because their group scored highest. They did not. A different team built a shelter so neat Ava stared at it with open envy. Jasper liked the moment the magic failed and the structure did not. Tidefall had spent all year teaching the same lesson in different forms. Do not build a life where one powerful thing has to work perfectly. Not a mysterious presence in the sea. Redundancy, Ava called it when Jasper said this aloud. Harper called it having backups. Mia called it common sense. That evening, the Year One Build shelters remained on the practice lawn for younger visiting families to inspect during end-of-year weekend.

The trio walked past theirs after dinner. A tag hung from the entrance: GROUP 4 - STABLE UNDER TEST CONDITIONS, Harper added with pencil: ALSO BEAUTIFUL. Ava tried to erase it. Ward walked past and said, "Leave it." Harper looked victorious. Harper blamed censorship. The shelter stayed up through the night. At breakfast, they learned a gull had stolen the tag.
