The Elves had mounted a tremendous arbalest on the deck, a construction on a wooden stand. A wide bow, a big lever of the straining mechanism, a steel trigger. There was a stack of missiles for that construction, long lances with feathering at ends. Bunches of usual small arrows had been brought and piled up too.

"Three humans co-operate with trolls," Jim worriedly informed them, "they are going to pursue us in some airship, as I heard…"

"An airship? A gigantic flying bean-pod they call a zeppelin? Well, we'll see…" the reply expressed no particular disquiet of the Elves, they looked ready for any trouble.

But all of them were quite attentive when passing the gateway channel between the watchtowers, leaving the fortified lagoon and going out into the open sea.

The troll flotilla had been awaiting for them within an easy reach from the coast line. This time the hostile boats flocked together and rushed to attack as a united pack, far outnumbering the yacht defenders.

Having deviated from several hurled javelins which flew over them and stuck into the deck, the Elves met the approaching enemies with a shower of arrows, shooting uninterruptedly and not missing.

The quivers getting empty quickly, Jim helped the archers to unbind the additional bunches of missiles.

In a minute the fight was over, hoarse snarling and screaming of monsters changed into silence, and the unruled boats drifted away without crews.

Then an increasing low rumble became heard. A grey sinister silhouette, a titanic zeppelin was moving towards them flying not very high above the sea, throwing a long shadow onto the water surface.

"The airship," Jim muttered when the apparatus lowered to them, and the bulky balloon covered seemingly a half of the blue late afternoon sky, two large propellers thundering.

The three knights leant out of the wooden gondola, their physiognomies grinning viciously, and threw a long thick rope with a massive iron hook at its end. That piece of metal thudded onto the deck, scratched the planks and caught hold on the board at the prow, near the bowsprit. The rope stretched tight, and the airship started tugging the yacht towards the shore.

"They want to smash us against the coastal rocks!" Jim took his battle-axe and dashed to hew the rope, but it turned out to be too thick and firm to be cut quickly.

Two Elves pulled the straining mechanism lever, another two loaded one of the huge arrows onto the enormous crossbow and, rotating that weapon on its stand, aimed it at the zeppelin.

The immense missile launched with a swish and pierced the balloon through.

Quickly reloading the arbalest, the Elves went on shooting over and over again, making more and more new holes.

The hot gas which had been keeping the apparatus in the air now was leaking, gushing out of gaps with torrents of steam. The zeppelin began to lose height.

The tension of the rope weakened, the Dwarf finally separated it from the yacht and flung the hook overboard.

The airship plopped down into the water and started to sink gurgling loudly.

"In an hour or two we shall be at the island!" Jim declared cheerfully, taking the steering-wheel and regaining the control over the yacht, making a turn and heading to the golden setting sun. "Maybe, Iven is already there."

"According to the plan," Sebastian pronounced, "we are gathering at the old portal."

"Can the enemy possibly get to the Dryads?" the Dwarf asked. "My friends went there without any key…"

"Who knows," the Elf replied, "usually only good-natured people are able to activate the transmission to our settlements, but we cannot be sure completely. Trolls are very perfidious."

"I don't quite understand that system of worlds," curiosity sounded in Jim's intonation, "are they different planets?"

"Some of them are, such as the human world and El Dorado," Sebastian explained, "but many of them are just isolated regions of one planet. For example, the constellations and the Moon at our Elvish realm and at the Dryad town are the same as here. Though, time zones don't coincide…"

"Isn't it miraculous!" the Dwarf admired, "even if you don't call it magic."

"It deals with special crystals which accumulate the solar energy and influence the space around the chosen land," Sebastian shrugged, "I'm not an expert, queen Veronica knows how it functions…"

"Well, travelling between planets and stars has been carried out through portals," Jim continued wondering. "Then, why do humans construct rockets and spaceships?"

"Actually, rockets are needed to launch satellites only," the Elf answered. "However, with few exceptions, humans are not aware of dimensions and portals…"
